PHP代码似乎死了没有获取数据

Question

here is my php code it gets the data, but seems to just die, it does echo the error codes I can;t seem to find the reason for this it was working at one point. this pulls data from an html form i can load it if needed.

thanks for looking.

    <?php
       if(isset($_POST['email'])) {

          // EDIT THE 2 LINES BELOW AS REQUIRED
          $email_to = "[e-mail]";
          $email_subject = "Runner Registration";


    function died($error) {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted.  ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }

        $gender = 'unchecked';
        $size = 'unchecked';

    if (isset($_POST['gender'])) {
        $selected_radio = $_POST['gender'];
            if ($selected_radio == 'male') {
                $gender = 'Male';
            }
            else if ($selected_radio == 'female') {
                $gender = 'Female';
            }
    }



    if (isset($_POST['size'])) {
